Profiling OpenGLContext on a relatively large VRML97 world.  Interesting stats (in OpenGL, ignoring OpenGLContext slow-points):

• 3% of total runtime is in a function which just does numpyarray.ctypes.data; it seems the ctypes array sub-object is a Python instance that has multiple operations in its initializer and is recreated on each access (with many accesses per array ...

Seems Nvidia has released OpenGL 3.0 drivers for Linux (yay!) but they don't support my GeForce 7600GS (sigh).  I'm thinking maybe I should buy a kick-posterior gaming laptop with an uber-3D chip so I'm not always tied to my workstation at home if I want to do OpenGL 2.0 or above work.

Anyway, tried to ...

Finally got my talk proposals in to PyCon.  I went for 3 this time, mostly because each of them seemed like it would be interesting enough to excite people.  I doubt all three will be accepted, but hey, maybe I can do a couple of them in Open Space.  I didn't propose the "graphics and ...
